The correct answer is A. 61.97894<\/strong>.<\/p>\n\n\n\n To calculate the molecular mass of sodium oxide (Na2O), we need to add the atomic masses of the elements that make up the compound. Sodium oxide consists of two sodium (Na) atoms and one oxygen (O) atom.<\/p>\n\n\n\n Now, we multiply the atomic masses by the number of atoms of each element in Na2O:<\/p>\n\n\n\n Finally, we sum these values to get the molecular mass of sodium oxide:45.97954\u2009g\/mol+15.9994\u2009g\/mol=61.97894\u2009g\/mol45.97954 \\, \\text{g\/mol} + 15.9994 \\, \\text{g\/mol} = 61.97894 \\, \\text{g\/mol}45.97954g\/mol+15.9994g\/mol=61.97894g\/mol<\/p>\n\n\n\n Thus, the molecular mass of Na2O is 61.97894 g\/mol<\/strong>, and option A<\/strong> is the correct answer.<\/p>\n\n\n\n In chemistry, understanding molecular mass is crucial for stoichiometric calculations, such as converting between moles and grams in chemical reactions. The molecular mass allows chemists to quantify substances and predict how they will interact in chemical processes.<\/p>\n\n\n\n The molecular mass of sodium oxide (Na2O) is A. 61.97894. B. 38.98917. C. 22.98977. D. 45.97954 The Correct Answer and Explanation is: The correct answer is A. 61.97894. To calculate the molecular mass of sodium oxide (Na2O), we need to add the atomic masses of the elements that make up the compound.
